9. Alignment / Balancing
Initial operation:
9.1. Fit sensor in pipe (ensure correct fitting location, see point 6 Mechanical
Connection).
9.2. Connection sensor cables to electronic circuitry (see point 7 Electrical
Connection).
9.3. Fill pipe with flow medium.
Caution! There must be no air bubbles on the sensor. Flow speed
must be at 0.
9.4. Commission electronic circuitry (switch on supply voltage)
9.5. Only on model KAL-E-3...Set temperature potentiometer (2) to left-hand
stop.
9.6. Zero point alignment. Briefly activate the "SET"key (5) (using a suitable
object e.g. ball point pen)
9.7. "Flow" LED (6) flashes for about 30 seconds. After this time the "Flow"LED
goes off (6). The device is now operational., continue with point 9.9.
9.8. In case of malfunction the "Flow" LED flashes continuously. Press the"SET"
key once again. Device will switch back into measuring mode. Check
mechanical and electrical installation and recommence operational
procedure from point 9.4.
9.9. Switches on installation and set maximal flow.
If the flow speed is significantly less then 2 m/s, then on the trend display (3)
there will be possibly fewer then 8 LEDs on.
It is now possible to extend this display (3) to the full range (8 LEDs). This can
only be successfully achieved, however, if the flow speed is somewhere between
0,25-1,8 m/s.
•
Set "Flow" potentiometer (1) (see illustration) to right-hand stop
(only on KAL-E3...; Set temperature potentiometer to left-hand stop)
•
Briefly activate SET key (5)
•
Flow LED (6) will flash for 30 seconds. After this time the Flow
LED will go 30 off.
